Definitions

• the invention refers to separation of solid materials by subsequent processing of the concentrate by flotation, and in particular - to the domain of the combined method of concentration of useful components of zinc, lead, gold and silver from complex ores of Zn, Pb, Au, and Ag with low percentage.
• the invention is sorted, i.e. classified and marked with classification symbols B03D 1/08 and B03B 5/28.
• the technical problem solved by this invention is: how to provide a commercial collective concentrate with Zn+Pb concentration above 50% from a low-percentage complex ore with high exploitations and minimal production costs for extracting Zn, Pb, Au and Ag by application of three-staged basic grinding and two-staged classification, conditioning, providing humidity in press-filters, basic and control flotation with usage of the operational control and process regulation system.
• Flotation concentration has a great significance and is widely applied as a branch of science, especially in the conditions of the exploitation of complex ores with lower and lower percentages.
• a very great number of exploitation methods are used, we will give some: gravitational, chemical, electro - magnetic, CIP (carbon in pulp) and many other combined methods.
• the new process enables valorization of more useful components: zinc, lead, gold and silver, which the processes mentioned above, are not able to do. Also, the new process progresses in parallel with the concentration of the minerals of copper, gold, silver, platinum and palladium, which gives good exploitations of Zn, Pb, Au and Ag and a final concentrate with a market value(Zn+Pb>50%).
• the invention refers to the process of extracting useful minerals of zinc, lead, gold and silver from small ore bodies of a complex ore.
• Mineralization is morphologically represented by regular lenses and wires, and the systems of the flotation concentration are of medium capacity.
• the process consists of several stages: three - staged basic grinding and two - staged classification, conditioning, basic and control flotation with exactly specified values of the kinetic constants for the whole period of time.
• the process of purification is flexible, so different concentrations of elements are used for two - , three - and four - staged purification. Listed possible technical - technological adjustments are conducted momentarily and without difficulties. Additional grinding of the control concentrate, separation of solid and liquid phases is done in the condensers and press - filters. Based on the element concentration in the concentration products and technical - technological parameters and the work of the plant on the whole on one side, and the general productions goals on the other, handling system of control and regulation of the process is used.
• Picture 1 represents the scheme of concentration of the polymetalic ore TENKA Majdanpek
• Picture 2 represents disposition of the automatics appliances
• Picture 3 represents the scheme of the filtration of the collective concentrate Zn-Pb in the press - filter
• Picture 4 represents the vertical cross-section of the press - filter. Detailed description of the invention
• the invention refers to the procedure of extracting useful minerals of zinc, lead, gold and silver from small ore bodies of a complex ore.
• the mineralization is morphologically represented by regular lenses and wire so the systems of the flotation concentration are of a medium capacity.
• the process of purification is flexible: o Two - staged purification is used in ore concentrating with proportion of Zn in the ore above 2,5% o Three - staged purification is used for the ore with proportion of Zn in the ore below o Four - staged purification is used in cases of increased proportion of Cu in the ore ranging from 0,30 to 0,40%
• An independent cell (MG - 8,5) is implemented in the grinder - hydrocyclone system, which separates large free grains of the useful minerals in order not to be returned to the grinder and over ground.
• working parameters of press filters are:
• the final product of the whole procedure is a collective concentrate ZnPb, which is the carrier of the noble metals Au and Ag.
